WATER-CLOSET.-

SPECIPICATION forming part of Letters Patent No. 362,034, dated April 26, 1887.

A pplicatinn filed June 19, 1886.

To all whom it may concern:

' Be itknown that 1, WILLIAM F. NORTH, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have'invented a new and useful Improvement in Water-Closets, which improve ment is fully set forth in the following specification and accompanying drawings, in which t Figure 1 represents a vertical section of a water-closet embodying my invention. Fig. 2 represents. a vertical section of a portion thereof at a right angle to Fig. 1. Fig. 3 represents a bottom view of a detached portion on an enlarged scale. Fig. 4 represents a vertical section in line a: :0, Fig. 3.

Similar letters of reference indicate corresponding parts in the several figures.

My invention consists of improvements in water-closets, as will be hereinafter fully set forth.

Referring to the drawings, A represents a water-closet bowl, having at top a rim, 13, forming a passage, 0, for water. At the bottom of the bowl is a valve-chamber, D, which is connected with said bowl and the soil-pipe E, and communicates therewith.

F represents a downwardly-opening valve, which is located within the chamber D and pivoted to the wall thereof. Fitted to the valve are laterally-moving locking-pieces G, which, when the valve is closed, enter recesses H in the sides of the chamber D, whereby the valve is firmly supported and tightly closed and locked. The pieces G are recessed near their inner ends, as at 11, leaving blocks J with inclined faces, with which faces engage inclined projections K on a slide, L, which is located between the upper and lower plates of the valve.

M represents a lever, which is mountedon the bearing pin or axis N of the valve, and having at its pivotal portion a cam, P, which bears against the slide L, so as to move the latter when the valve is to be lowered, the effect of which is the unlocking of the pieces G from the walls of the recesses H. One limb of the lever M bears against the under side of the valve, and the other limb is pivoted to a link, M, to which latter is pivoted a handled rod, Q, by which the valve is operated.

Serial No. 205,683. (Nomodch) water cannot escape from the bowl, and sewergas is prevented from returning to the bowl.

When the rod Q is raised, the cam P, rotating with the lever M, moves the slide L, so that the pieces G are withdrawn, and as the valve is no longer held by said pieces it drops, and is accordingly open, whereby the contents of the bowl are discharged. WVhen the rod is let go, the lever M, actuated by the weighted arm R, quickly raises the valve, and the slide L, no longer controlled by the cam P, is returned to its first position by the action of the springs T,each of which bears against the. block Jof one of thepieces G and the head of the'other piece G, so that both pieces are forced outwardly and directed into the recesses H, whereby the valve is again heldin locked position.

Connected with the tank or cistern S is an outlet-pipe, A, which leads to the bowl A, and also connected with said tank is a supplemental tank, S*, which has an outlet-pipe, A

the latter being in communication with the pipe A. Rising from the pipe A is a valveseat, A, and rising from the tank S is a valveseat, A, said seats being turned inwardly at top, so as to form close joints with the valves W \V, which are formed of rubber or other soft material and secured to the head X, which, by means of a rod, X, is connected with the lever S. Depending from the head at the side carrying the valve V-is a rod, Y, to whose lower end is secured a valve, Z, whose seat Z is at the bottom of the tank S or top of the pipe A When the lever S is raised, the valves W WV are opened and the valve Z is closed. Water now flows'through the pipe A and washes the bowl, and the tank S is also filled, the water in the bowl passing through the open valve F to the sewer or cesspool. \Vhen the valve F ICO closes, theleverS returns to its normal position, whereby the valves W W close and the valve Z opens, whereby the waterin the tank S flows through the pipe A? and enters the bowl, remaining thereon as a seal.

Buffers F, of elastic or flexible material, are secured to the valvechamber D in such position that when the valve drops it strikes said buffers, the latter acting as stops and preventing noise, which would otherwise be occasioned should the valve directly strike the wall of the chamber. a

Should the springs T fail to hold the pieces G in the recesses H, the weight It of the arm R, forcing down the link M, causes the upper 'limb of the lever M to bear firmly against the valve, whereby the latter is unfailingly held closed onits seat.

The upper end of the link M, which receives the lower end of the rod Q. is recessed, the walls of which abut against the rod and limit the lateral play of said link, so that it does not strike the walls of the chamberwithin which it is located.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a watercloset, the hinged valve F, with axis N, in combination with lever M, mounted on the axis N and provided with an upper arm adapted to support said valve F, a link and rod'eonneeted to a lower arm ofsaid lever M, fastening devices for said valve, substantially as described, and a cam for operating said fastening devices, all substantially as described. a

2. The chamber D, with recesses H, the locking-pieces G, with blocks J, slide L, with projections K, and springs T, combined and operating substantially as and for the purpose set forth.

3. The valve having sliding pieces G and a slide, K, which engages with said pieces, in

combination with a cam which operates said slide, substantially as and for the purpose set forth.
